Silencers no longer decrease the muzzle velocity and are generally less effective when used with normal ammunition. They now only remove the muzzle blast and flash. To prevent the crack caused by super sonic projectiles, ACE introduces sub sonic ammunition. This is also fully compatible with AI. Sub sonic ammunition is available for the calibers 5.56mm, 6.5mm and 7.62mm.
Armour piercing rounds have higher penetration values against light armoured targets or other obstacles on the battlefield. Their drawback is a slighly decreased man-stopping power. AP rounds are available for the calibers 5.56mm, 6.5mm and 7.62mm.
Flash suppressors are similar to sound suppressors and prevent the muzzle flash reducing visibilty without decreasing combat effectiveness. Flash suppressors are available for the calibers 5.56mm, 6.5mm, 7.62mm, .45 ACP and 9mm.
